As discussed in our article recently published by Law360, criminal health care enforcement in 2019 was in many ways a continuation of 2018, with opioid-related enforcement continuing to be the clear top priority for the Department of Justice (DOJ), in addition to DOJ's sustained focus on prosecuting individuals and data-driven identification of health care fraud.  This post provides an overview of our article, which covers these issues and our expectations for 2020 in detail.

Criminal healthcare enforcement in 2018 once again focused heavily on opioids, targeting manufacturers, prescribers, dispensers and those who contribute to the addiction epidemic, and on prosecution of individuals for a variety of offenses.  In addition, the DOJ announced some expected policy changes related to the way it investigates and prosecutes corporations as well as the restrictions placed on corporations after resolution of government charges.  We will address each of these issues in this post and will attempt to forecast what we expect to occur in the coming year.
